摘要： A method and apparatus fluidizes solid deposits of coal tar sludge, such as coal tar decanter sludge or coal tar tank sludge to a relatively homogeneous mixture of solids dispersed in liquid. The coal tar decanter sludge received from the coke oven, including approximately 10 to 50% by weight coal and coke solids, is conveyed into a sludge mixing vessel where it is deposited onto a liquid-permeable support member or screen having a predetermined maximum screen size. A suitable coal tar solvent in the sludge mixing vessel is heated to a temperature sufficient to partially solubilize and reduce the viscosity of the coal tar portion of the coal tar decanter sludge to provide a pumpable dispersion of solids dispersed in a diluted coal tar mixture. Agglomerates of coal and coke solids held together with coal tar fall through the screen when sufficient coal tar has solubilized and the solid agglomerates then are reduced in size for recirculation to the sludge mixing vessel. The diluted coal tar mixture is pumped to recirculate it to the sludge mixing vessel after impacting and shearing the solid agglomerates to reduce the solids particle size.

摘要： Pitch is produced continuously by heat treating a heavy hydrocarbon oil at a temperature of 350.degree. to 500.degree. C successively in two or more reactors connected in series, outlet to inlet, recirculating, at the same time, one portion of the liquid output substance from at least one reactor into that reactor, and introducing the output substance (molten pitch) of the final reactor into an after-treatment chamber of duct shape with an inactive atmosphere sealed therewithin thereby to cool the output substance.

摘要： A method (100) of recovering tar from the gasification of a carbonaceous feedstock includes gasifying (12) a carbonaceous feedstock (14) to produce a raw gas (20) which includes at least CO, H2, tar and entrained solids, the raw gas (20) being at a temperature of at least 250° C. and a pressure of at least 15 bar (g). The raw gas (20) is quenched and washed (22) with a quench liquid (24) producing a solids-containing liquid stream (32) which includes tars, the solids-containing liquid stream being at a temperature of at least 150° C. and a pressure of at least 15 bar (g). Solids (56) are separated (46) from the solids-containing liquid stream (32) to provide a tar recovery stream (102). The tar recovery stream (102) is treated by at least cooling (34) and pressure expansion (36) thereof to produce a tar stream (58).

摘要： In a system for thermal cracking gaseous feedstocks, the system including a gas cracker for producing an effluent comprising olefins, at least one transfer line exchanger for the recovery of process energy from the effluent and a water quench tower system, a process for extending the range of system feedstocks to include liquid feedstocks that yield tar is provided. The process includes the steps of injecting a first quench fluid downstream of a primary transfer line exchanger to quench the process effluent comprising olefins, separating in a first separation vessel a cracked product and a first byproduct stream comprising tar from the quenched effluent, directing the separated cracked product to a water quench tower system and quenching the separated cracked product with a second quench fluid to produce a cracked gas effluent for recovery and a second byproduct stream comprising tar. An apparatus for carrying out such process is also provided.
